ISPConfig & Godaddy Namservers.

[swarm]

I have a dedicated server at a hosting company. I have 1 IP address with them. I have a domain dsmtuners.net. I need to make DSMTuners.net resolve to the IP and for it to serve files. I found http://www.howtoforge.com/ispconfig_dns_godaddy , but after completing those steps, things just don't work.
I get:
root@host:/var/www# dig @ns1.dsmtuners.net any www.dsmtuners.net

; <<>> DiG 9.3.4 <<>> @ns1.dsmtuners.net any www.dsmtuners.net
; (2 servers found)
;; global options: printcmd
;; connection timed out; no servers could be reached


I really need help getting this setup. Anyone willing to assist?

mh1:~#Are ns.liquidweb.com and ns1.liquidweb.com your own nameservers, or do they belong to your ISP or domain registrar? Because that's where you have to create/modify your DNS records.
